What are the original carbs you are trying to mimic? From the Carter book for the 1959-62 V8 they list the 2798 Frt and 2799 Rear for the 59 383 and 413.
Primary both are .089. The front Sec are .067 and the rear sec .055
These were 1 7/16 P and 1 9/16 S throats Idle jet .031 on both. Idle vacuum 19.5"
the carb numbers i have are 2970 and 2971, but jetting appears to be the same as the 2798/2799. those small throttle bores would have small venturii (especially the secondaries compared to the edelbrocks) and the listed metering rods and small jets would be near impossible to find.
